The present invention relates to a locking mechanism for guarding the doors or closures of safes, vaults and the like andhas for its object to provide an improved arrangement '5 of operating` and control elements :tor` the locking mechanism which aifords a compact, simplified and practical arrangement, economical to manufacture and convenient to operate. y

A further object of the invention is to provide in safes, vaults and the like having boltwork for securing the doo-rs or closures thereof and having a combination lock for protecting the bolt-work, an improved arrangement of operatingdevices combined or associated in such a manner that each is rendered operable through a common opening formed in the door or closure, one to control the combin ation lock and theother the bolt-work.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be'hereinafter more fully described, the novel features being pointed out in the claims at the end of the specilication.

In the drawing:

Fig. 1 is a view in elevation looking at the rear side of the door and showing the general arrangement of one embodiment of the invention;

Fig. 2 is ay sectional elevation drawn to an enlarged scale and taken on line 26e-2a of Fig. 1;- v y Fig. 3 is a sectional plan through the safe door showing the relationship of the combination lock and control parts on the opposite sides oi" the door, and l Fig. t is a front elevation of the dial and operating handle for controlling the combination lock and bolt-work.

Similar reference numerals throughout the several views indicate the same parts.

The present invention embodies means for effecting control through a single opening in the saie door, of the bolt-work at the inner side thereof and a combination lock for protecting the same, also located upon the inner face of the door'. One advantage of this arrangement isthat it eliminates the more or less expensive operation of drilling one of thev openings through the relatively thick wallof the door heretofore required for the reception-of the operating spindle for the bolt-work.

A further advantagein eliminating one of the openingsis thatit reduces the number of point-s of attack byvthose attempting to gain access to the bolt-work forzthe Vpurpose of releasing the same withthe idea of robbing theI safe. Y y

A' further advantage lies in the' fact that with the present arrangement if the combination dial spindle is driven inthe external *operating means vfor: the' bolt-work is de' stroyed, whereas with the arrangement now 1n use thls spindle remains intact and.per

mits the bolt-work to be readily shifted-to-re-V, lease position after the combination lock has e been rendered inefectiveas a means for protecting the bolt-work. i

A Stillv further advantage'in combining the control devices lies in the fact that thedial spindle is used as a mounting vfor the operating handle and spindle for shifting the bolt f work7 whereby a reduction in the number of parts is etl'ectedand likewise the cost of manufacture Referring to the drawing 10 represents a portion .of the wall of a safe, vault, or other container, and 11 the door or closure therefor. The doormay beprovided with any suitable type of bolt-work such for example as that illustrated in Fig. 1, which comprises a. plurality of bolts 12 supported by guides 134011 the door and varranged to take into openings ormedinthe door jamb or plate member 14 secured theretol in any lsuitable manner. The bolts are connected by a carrying bar `15 having a locking dog 16 thereon guarded or protected against release by suit- V*able means such as, the combination llock bolt 17 shown projecting from the lock casing 18 in the-path of the dog 16. The casfee ing carries a tumbler spindle 19fon'which any suitable number of tumblers 20 are mounted and provided with the usual notches 21, which when brought into registry by thesuccessful Operation `of the combinationfpermit the laterally projecting pin.

22 Onthe pivoted arm or gate 23 to drop therein. In this position of the parts the lug 24 on the gate engages an abutment 25 on the bolt operating dish 2G secured on the tumbler spindle, whereby upon rotation of the spindle in an anti-clockwise direction as viewed in Fig. 1, the bolt 17 will be withdrawn to release the bolt-worli- Operation of the tumbler spindle is effect'- ed through a gear 27 thereon, the teeth of` which are in mesh with those of a similar gear 28 on the spindle 29 extending through an opening in the safe door and provided with a dial 3() having an operating knob 31, the dial being associated with the usual dial plate 32 as shown in Fig. 2. The dial spindle is of tubular construction and has eX- tended within its outer end a projection 33 on the dial which is suitably secured to the ,fi-spindle, as by means of the pins 34, Fig. 2. The inner end of the spindle is preferably threaded to receive the gear 28, the latter having a hub 35 journaled in a supporting plate 36 on the rear face of the door. The gear 27 is preferably provided with a hubV 37 also journaled in the plate 36, the lat-ter forming a support for the casing 18 as shown in Fig. 3. The gear 28 is prevented from working loose on the spindle by means of a key 38 applied as shown in Fig. 2.

The operating means for shifting the bolt work to and from locking position comprises a rack bar 39 connected with the bolt carrying member 15 and guided by a lug 40 on the door, the teeth of the rack bar meshing with those of a segment 41, the lower end of which is rigidly secured on the squared portion 42 ofv an operating spindle 43 entending through the dial spindle as shown in Fig. 2. The spindle 43 at its outer end is journaled in the dial or dial knob and is provided at its inner end with an enlarged bearing portion 44 journaled in the dial spin dle. The operating handle 45 for the spin4 dle 43 is provided at its inner end with an annular portion 46 seated in a recess formed in the dial linob 31, the spindle 43 having sufficient play to permit of free and easy rotation of the dial spindle when operating the combination. The gear segment 41 is clamped upon the spindle 43 by means of the nut 47 threaded on the reduced end portion of the spindle and secured against turning by a key 48.

In the operation of the mechanism, assuming that it is desired to unlock the safe, the operator will rotate the dial thereby rotating the gears 28 and 27 which effect rotation of the tumbler shaft to bring the notches of the tumble-rs into aline-ment. The projection 22 on the gate 23 will then be in registry with the notches, thus permitting the gate to drop and the lug 24 thereon to assume a position in engagement with the abutment 2.5 on the operating disk 26 which is secured to the tumbler shaft. Continued rosi red to loclr the door the handle 45 is turned 'i' to advance the bolt-work to locking position, after which the dial knob is turned to destroy the combination, during which operation the bolt 17 has advanced to locking position with respect to the dog 16 on the bolt carrying bar 15.

Idhile I have provided gearing between the dial spindle and the tubular shaft for operating the latter it will be understood that other suitable means may be provided for this purpose if desired. Furthermore although I have shown a. rack and segment for shifting the bolt-work to and from locking position it will be understood that any other suitable means may be vprovided for this purpose if desired.
